"Though an army besiege me, my heart will not fear; though war break out against me, even then will I be confident." Psalm 27:3
Fear is the flipside of faith. Therefore, if you can do fear you have what it takes to do faith!
The difference between fear and faith is your focus.
David, the Psalmist, refused to give into his fears. Since he chose not to fear what was left for him?
FAITH! The HOLY fear!
Rather than focus on the advancing army of King Saul and fret over the harm that could befall him, he chose to be confident in the Lord!
He wasn't delusional nor was he psyching himself up with happy talk. He looked at what was against him and he looked at Who was for him and decided he had nothing to fear.
As the great verse in Romans 8 declares, "What, then, shall we say in response to this? If God is for us, who can be against us?" (8:31)
What WILL you say?
Is God for you?
Is God Who He says He is? Does He honor His Word?
Then what is there to fear?
Fear is the weapon of the enemy. If he can cause you to fear he can keep you from focusing on faith. But God gave you His Word and God sent His Son to defeat the enemy and deliver you from fear.
Death is the other weapon the enemy tries to use against you to get you to fear. But again, God defeated death when His Son, Jesus, died on the cross and arose on the third day! Death is conquered so why would you fear it?
As a person of faith and follower of Christ, you have been given abundant life (John 10:10) and eternal life (John 3:16). Therefore, you can live in faith above your fears and the your last moment in this life becomes the first moment of your REAL life in eternity!
So, what are you afraid of?
If you can believe in the things that cause you to fear then you have what it takes to believe the things of faith! And, if you can have faith part of the time you can have it all the time!
